Adding thousands separator to variable with a period in its name in Javascript

Question

I'm not too familiar with Javascript so there's probably a really simple solution to this. All I want to do is add comma thousands separators to the output of this function:

function() {
return '$' + this.value;
}

So, for instance $100000 will display as $100,000. My problem is that I don't know how to deal with the variable this.value because of the period.

I tried:

function numberWithCommas(this.value) {
    return '$' + this.value.toString().replace(/\B(?=(\d{3})+(?!\d))/g, ",");
}

My guess is that this.value.toString() is not proper syntax.

Thanks in advance.

Hope it will help you:

var n = 1123456789.123
n.toLocaleString()
"1,123,456,789.123"

See more: toLocaleString

You can use: Numeral.js - it is very powerful

And: in the future, you really research and try again and again.

Thanks

This worked:

function numberWithCommas() {
    return '$' + this.value.toString().replace(/\B(?=(\d{3})+(?!\d))/g, ",");
}
